How Should We Then Live?

This narrative by Francis A. Schaeffer was probably the most difficult capture/transfer ever.

(Note: Clicking pictures will play videos)

First of all, the original VHS was encoded with Macrovision copy-protection system. So there was a need to research for a patch for video capture device driver. Surprisingly, the patch does nothing more than making the main driver to ignore the Macrovision (the original behaviour was to detect Macrovision and to record trash to the disk file while continuing to capture video seemingly no-problem!)

Here’s what’s believed to be a Macrovision artifact:

(see the brightness sharply going down at one point. In other places the brightness goes similarly up)

Then, the video source was the true NTSC telecined film (3:2 pulldown)…

And 3:2 pulldown means you cannot just deinterlace the video, you have to IVTC it (make InVerse TeleCine) instead.

Some may argue that there is a standard filter for that in the VirtualDub. Yet it’s unusable on long clips - the AviSynth overflows stack while processing. Video has to be cut into parts of up to around 50,000 frames each.
